Abstract
Light-in-flight recording by holography is a technique for recording a motion picture of light propagation. The technique uses an ultrashort pulsed laser to record a hologram. An ultrashort light pulse emitted from the laser is divided into two pulses. One pulse, called as the reference light pulse, is obliquely incident to the holographic plate. The other is incident to the diffuser. The light pulse from the diffuser is called as the object light pulse. The recordable time of the motion picture is limited by the lateral length of the plate. Then, we propose a technique for extending the recordable time. This technique uses double reference light pulses and dividing the plate longitudinally into two parts. Two motion pictures of the light propagation can be continuously recorded on the plate with a single-shot exposure, so that the recordable time of the motion picture can be extended. We succeeded in extending the recordable time up to twice using the proposed technique.
